JAMES B. SHERIDAN, OF PITTSBURGH, PENNSYLVANIA.

WINDOW-VENTILATOR.

To all whom it may concern:

Be it known that 1, James B. SHERIDAN, a citizen of the United States, and a resident of Pittsbm'gh, in the county of Allegheny and State of Pennsylwrnia, have invented a new and useful Improvement in i VindowVentilators; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a window ventilator and has special reference to a ventilating device for store or show windows.

The object of my invention is to provide a cheap, simple and eflicient device for ventilating store, show and other windows whereby such device will prevent the interior surface of such windows from t'rosting and thus keep the windows from sweating, so that they will remain in their usual clear condition.

To these ends my invention consists, generally stated, in the novel construction, com bination and arrangement of parts, as hereinafter more specifically set forth and described and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use my improved window ventilator, 1 will describe the same more fully, referring to the accompanying drawing, in which Figure 1 is a front view of a portion of a building showing my invention applied thereto. Fig. 2 is an enlarged vertical section of the same on the line 22, Fig. 1. Fig. 3 is a front view of a portion of a building showing another form of a window having my invention applied thereto. Fig. 1 is an enlarged vertical section of the same on the line 4- 1 Fig. 3.

Like symbols of reference herein indicate like parts in each of the figures of the drawing.

[is illustrated in the drawing the numeral 1 indicates a show-window of the ordinary approved construction in the building A which is provided with the top 2, bottom 3 and glass 4. set within the same. The glass 4t is positioned in the usual manner within the framework 1, and at its bottom and sides between the usual outside and inside strips 5 and 6 respectively, while the upper or top part of such strips are so arranged as to a passage-way 7 around the upper edge of the glass 41 which leads from the open air Specification of Letters Patent.

or atmosphere into the show-window 1. The upper edge of the glass l extends slightly above the lower edge of the outside strip 5 in forming the passage-way i l and the lower edge of the inside strip (.3 extends below the upper edge of said glass and somewhat lower than said edge and the lower edge of the outside strip to form a deflector 6 for the chute 8 leading from said passage-way. ithin the panel 9 above the window 1 are the usual supporting beams 10 and around such beams and above the framework 1. a conductor 11 extends from within the window l and under the top 2 of the same. This conductor extends upwardly in the building A from. the beams 10, so as to open unto the atmosphere under the ordinary upper window Z) as at 12, and is provided with a suitable covering or grating 13 over said o .)ening 12, or it can connect with a conduit 12 having air holes 12 which are below said window and lead to the air.

The use and operation of my improved window ventilator is as follows :-Gold air from the atmosphere will enter the passageway T around the upper edge of the glass 4 and will be deflected down along and against the interior sru'face of the glass from the chute 8 connecting said .)assageway by the deflector (5. As such air passes down along and against the glass it such cold air will become heated from the ordinary conditions in the show window 1, and after such air has reached the bottom of the said glass it will rise on account of its heated state or condition, so that it will enter the conductor 11 at the upper end of the said window and. thence pass from the same out into the atmosphere therefrom.

When av transom or upper glass is used in the show window 1, such as is shown at 1 1: in l? 3 and 4, and it is desired to keep the same free from frosting, as well as the show glass 4, the passage-way 7, chute 8 and deflector 6 is used at the upper edge of such glass and the upper edge of the glass 1 is positioned or secured in the dividing strip 15, and in such case a deflecting plate 16 is secured to the inner face of such strip. This plate 16 is separated from such strip to form a passage-way 7 between the same and is provided with a funnel and lower deflecting portion 16 and 16 thereon, which portions are respectively turned from and toward the glasses 4t and 14:, in

order to respectively catch and deflect the cold air entering the window from the atmosphere through the passage-way 7 and chute 8 after it has passed down along the glass 1%, into the passage-way 7 and against the glass f, after which and becoming heated it passes upwardly and out to the atmosphere through the conductor 11, as hereinbefore described.

It will thus be seen that in the use of my improved window-ventilator, all liability of the windows frosting will be overcome and therefore a clear glass will be presented at all times, while at the same time the sweating of the windows will be thus prevented and thus eliminate any liability of condensation taking place from such frosting and having to provide means for carrying ofl such water incident to such condensation. It will also be seen that my improved window ventilator will insure currents of air being directed to the particular points on the glass to equalize the temperature and prevent the frost on such glass without admitting sufficient air into the room or window as would perceptibly reduce the temperature and make it uncomfortable. It will further be seen that the window ventilator will have the outside air continuously passing over the entire inner surface of the glass in the window and will prevent any moist warm air in the building from coming in cont-act with the glass, which will thus prevent the accumulation of moisture and ice on the windows in which the ventilator is used.

My improved window ventilator is shown and described in connection with show windows but it will be evident that the same is applicable to all inclosed windows where it is desired to prevent the collection of moisture, frost or ice, while various modifica tions and changes in the design and construction of the ventilator may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

What I claim as my invention and desire to secure by Letters Patent is 1. In combination, a window having a glass therein and an air passage-way above the glass leading from the atmosphere and communicating with the interior of the window, a deflector for directing the air from said passage-way down and along the interior surface of the glass, and means above said passage-way for conducting the heated air arising from within the window to the atmosphere.

2. In combination, a window having a glass therein and an air passage-way above the glass leading from the atmosphere and communicating with the interior of the window, a deflector for directing the air from said passage-way down and along the interior surface of the glass, and a conductor above said passage-way for conducting the heated air arising from within the window to the atmosphere.

3. In combination, a window having an upper and lower glass therein and an air passage-way above the upper glass leading from the atmosphere and communicating with the interior of the window, a deflector for deflecting the air from said passage-way down and along the interior surface of the upperglass, means supported between said glasses and adapted to form a passage-Way between the same and its support for directing the air from the upper glass down and along the interior surface of the lower glass, and means above said first named passageway for conducting the heated air arising from within the window to the atmosphere.
